Answer:
Step-by-step explanation:
MX = XN
5r² + 2r + 52 = 4r² + 12r + 27
5r² - 4r² + 2r - 12r + 52 - 27 = 0
r² - 10r + 25 = 0
(r - 5)² = 0
r - 5 = 0
r = 5
4r² + 12r + 27
4•5² + 12•5 + 27
4•25 + 60 + 27
100 + 60 + 27
187
The Second one
I hope I helped you.
V = pi*r^2*h
V = 490
h = 10
490 = pi*r^2*10
r = 3.95
Answer:
3.2 plz help me to
Step-by-step explanation:
Answer:
y = - 1/3 +2
Step-by-step explanation:
✯Hello✯
↪ first we need to rearrange this so the answer is equal to Y
↪ -3x on both sides
↪ 9y =-3x+18
↪ then divide by 9 to get y on its own
↪ Then we can simplify the answer -3x+18/9 further so the 2nd option is the answer
